Specification of Letters Patent.

Patented Mar. '7, 1916.

Application filed July 7, 1915. Serial No. 38,462.

To all whom it may concern:

v 4 or the Be it known that 1, JOHN L. KOLIHA, a citizen of the United States, residing at Schuyler, in the county of Colfax, State of Nebraska, have invented certain new and useful Improvements in Door-Hinges; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a door hinge.

An object of the invention resides in the provision of a hinge by means of which a door, after having been once hung can be raised or lowered to relieve its binding at the top or bottom or can be pushed away from or drawn toward the hinge jamb so as to relieve it of binding on the lock side or the hinge side.

A further object of the invention resides in so constructing the hinge that it need not be removed from either the door or the jamb to secure such adjustments.

With these and other objects in view, such as will appear as the description progresses, my invention comprises the combination and arrangement of parts as set forth in and falling within the scope of the appended claims.

Referring to the drawing: Figure 1 is an elevational view of a hinge constructed in accordance with my invention, showing the same attached to a jamb and a door, only a portion of the door and jamb being shown, however. Fig. 2 is a sectional view through one of the adjusting buttons. Fig. 3 is a sectional view, showing the positions of the holes in the hinge and the relation of the adjustment cams thereto. Fig. 4: is a sectional view of a modification of my device. Fig. 5 is a plan view of a modified form of a hinge plate. Fig. 6 is a sectional view on line 6-6 of Fig. 5. Fig. 7 is a vertical sectional view with the buttons in place upon the hinge plate, the section passing through two of the buttons. Fig. 8 is a bottom plan view of one of the buttons, showing the groove therein.

" Referring to the drawing wherein like parts are indicated by like characters throughout the several views: I have shown my device secured to a j amb 1 and a door 2. The hinge consists of a plate 3 secured permanently to the j amb 1 by means of screws like and a plate 5 hinged to the plate 3 and secured to the door 2 in a manner which I will now describe. The plate 5 1s proyided with a plurality of holes-6, 7 and 8 which are of circular formation. The

:center of the hole 6 is a greater distance from the hinge edge of the plate 5 than is the center of the hole 8. This plate 5 is secured to the door 2 by screws 9, which pass loosely through buttons 10, 11 and 12 and penetrate the door. When these screws are tightened the buttons, being of a greater diameter than the holes 6, 7 or 8, will bind against the outer face of the plate 5 and secure it to the door.

In order that the door may be adjusted after having been once hung, I have formed, on the inner faces of the buttons 10, 11 and 12, cams 13, 14 and 15, respectively, which are operable in the holes 6, 7 and 8, respectively, and move about the screws 9 as pivots. These cams are so arranged that they will engage the edges of the holes in the manner clearly illustrated in Fig. 3 of the drawing. Now assuming that the upper. corner of the lock side of the door binds against the adjacent jamb and the cams are in the positions shown in Fig. 3 of the drawing to adjust the door so that it will again hang straight it is necessary to first loosen the screws 9 to destroy the binding action ofthe buttons. The button 12 is turned so thatthe cam 15 will be moved in the direction of the arrow in Fig. 3 of the drawing. This will force the upper end of the door towardthe hinge jamb 1 and will relieve the binding. The screw 9, which passes through this button 12, is then tightened. The cam 13 is moved to a position similar to that shown in Fig. 3 of the drawing and the screw 9 passing therethrough tightened. The weight of the door will be practically supported by the cams 13 and 15 inasmuch as they extend substantially vertically downwardly and therefore but a small portion of the strain is applied to the cam 14 after the screw 9 which passes therethrough has been tightened. "Now should it be desired to move the upper end of the door away from the hinge jamb 1 the cam 13 will be turned in the direction of the arrow in Fig. 3 of the drawing, which action will cause the cam to ride'upon the edge of the hole 6 and, since the plate 5 will have no movement away from the j amb 1, will move the upper end of the 'door'away from the j amb. When it is desired to move the door upwardly the cam 14 is moved about its pivot in the direction of the arrow shown in Fig. 3 of the drawing, which action will obviously raise the door. It will thus be seen that upon the adjustment of the proper cam the door may be either raised, pulled toward the hinge jamb or pushed away from the same. In order that the operator may know just exactly the location of each cam, I have provided each of the buttons with an indicating mark 16 which lies directly over the end of the cam which engages the edge of the hole in which it is located.

In the modification of my device shown in Fig. i of the drawing the hinge plate 5' is provided with a plurality of holes 6 which are located in the plate in positions similar to those occupied by the holes in the plate 5 in the embodiment shown in Figs. 1 to 3 inclusive. Each of these holes 6 is provided with an enlargement 7, the edge of which is provided with a plurality of serrations 8. In this form the buttons are provided with inwardly extending shanks 9, on the inner ends of which cams 10 are formed, which cams are of similar formation to the cams in the preferred embodiment. The ends of these cams 10 engage in the serrations 8 and thus maintain the cams in their adjusted positions, securely. The operation of this form of my device is similar to the operation of the form shown in Figs. 1 to 3 inelusive.

In the form of my invention illustrated in Figs. 5 to 8 inclusive I have provided a hinge plate 5 which has an octagonal hole 6 adjacent the upper portion thereof, a similar hole 7 adjacent the lower portion 7 thereof and in alinement with the upper hole and a similar hole 8 located midwa between the first mentioned holes and in oft set relation thereto. Formed on the plate 5 adjacent the upper edge of the hole 6 is a spur 9", adjacent the lower edge of the lower hole 7 is a spur 10", while adjacent the outermost edge of the holes 8 is a spur 11". These spurs 9", 10 and 11" are of wedge-formation, as clearly illustrated in Fig. 6 of the drawing and are of slight arcuate formation, the centers of the holes being the centers of the arcs as clearly illustrated in Fig. 5 of the drawing. This plate 5 is adapted to be secured to the stationary hinge plate in a manner similar to that in which the plate 5 of the form shown in Fig. 1 is secured and is adapted to be secured to the door in the following manner: Extending through the holes 6, 7 and 8 are screws 12 which project beyond the outer face of the plate 5 and have buttons 13", 14 and 15 rotatably mounted thereon. Each of these buttons is provided with a helical V-shaped groove 16 in its inner face into which the adjacent spur of the plate 5 extends. The door may be adjusted by the coeperation of the spurs with the grooves in the buttons. It will be readily seen that by turning the proper button the hinge plate 5 and the door on which it is mounted will be adjusted inasmuch as the spur will ride in the groove in the button and the screw 12 being stationary the plate 5 will be caused to move, as the spur moves toward or away from the center of the button. It is to be understood that the grooves in the buttons may be of various formations and the spurs may be arranged about the holes in greater number or in different relationship as the formation of the grooves is changed.

From the foregoing description it will be seen that I have provided a hinge by means of which a door may be adjusted after having been once hung without necessitating the removal of the hinge or unnecessarily marring the door.

While I have illustrated and described a particular embodiment of my invention it is to be understood that I do not want to be limited to that particular embodiment, as it is obvious that numerous changes, such as the increasing of the number of the adjusting buttons and the formation of the cams may be made without departing from the spirit of the invention or without in any way exceeding the scope of the claims.

What I claim is 1. In a hinge, the combination with a plate adapted to be secured to a stationary member, of a second plate hinged thereto, the said last mentioned plate being adapted to be secured to a door and having a plurality of holes therein, cams adapted to be secured to the door and located in said holes in such manner that they will engage the edges thereof and means for moving the said cams, whereby they will be caused to ride upon the edges of the said holes and adjust the door on the hinge.

2. The combination with a door, of a hinge mounted thereon, one plate of said hinge having a plurality of holes therein arranged in triangular relation with two of said holes adjacent the hinge edge of the said plate, cams pivoted to the door and lo cated in said holes in such manner that they will engage the edges thereof and means for moving said cams about their pivots.

3. The combination with a door, of a hinge mounted thereon, one plate of said hinge having a pair of holes arranged one above the other and adjacent the hinge edge and a third hole arranged in off-set relation to the first mentioned holes and between the same, the said holes being of circular formation, a cam pivoted in the uppermost of the first mentioned holes in horizontal alinement with the center thereof, but off-set toward the hinge edge of the plate, a cam pivoted in the lowermost of said first mentioned holes in horizontal alinement with the center thereof, but oifset away from the hinge edge of the plate, a cam pivoted in the ofiset hole in vertical alinement with the center thereof, but below the same and buttons formed on said cams by means of which they may be turned and the hinge clamped to the door.

4. In a hinge, the combination with a plate adapted to be secured to a stationary member, of a second plate hinged thereto and having a plurality of holes therein arranged in triangular relationship, screws extending through said holes and adapted to be engaged with the door, and buttons rotatably mounted on said screws and overlying said holes, the said second plate having spurs thereon adjacent the holes and said buttons having grooves therein into which said spurs extend.

5. The combination with a plate adapted Copies to be secured to a stationary member, of a second plate hinged thereto and adapted to be secured to a door, the said plate having a pair of vertically alined holes therein, a third hole in vertical off-set relation to the said pair of holes, spurs formed on the plate adjacent the upper and lower edges of the upper and lower holes of the said pair, a spur formed on the plate adjacent the outer edge of the third hole, screws extending through said holes and adapted to penetrate a door, and buttons rotatably mounted on the ends of the screws and lying adjacent the outer face of the second plate, the said buttons having grooves therein into which the said spurs extend.

In testimony whereof, I aflix my signature, in the presence of two witnesses.
